ABSTRACT:
For the purpose of blast-cleaning surfaces, in particular facades, a cleaning process and accompanying device have a working area with an air curtain and a suction device. The working area is tightly connected with the surface on one side via a contact opening and on the other side has a work opening through which the cleaning personnel can guide the cleaning jet nozzle while maintaining visual contact with the surface to be cleaned. The air curtain is formed along the work opening in such a way that no dust or blasting material can escape through the work opening from the working area.
